On the main road from Adliswil to Zurich, a new Mercedes-Benz showroom with garage services and seminar centre was to be built. The architectural idiom used in the competition entry, which was awarded second prize, is based on the clear images of late modernism.
Zürichstrasse, on the west side of which the large site to be developed is located, is the main connection between Adliswil at the lower end of the Sihltal Valley and the nearby city of Zurich. A design plan by Theo Hotz Partner AG dating from 2014 provided the basis for the planning. The proposal for the new Mercedes-Benz car dealership is a further element in a series of important large- scale contributions to urban development in the area Dietlimoos-Moosach that include the water supply, international schools, and existing car dealerships.
The design evokes the filling station in the south-west of Montreal designed by Mies von der Rohe in the 1960s. Areas of black metal sheeting and black enamelled glass structure the facade and bring the different parts of the car showrooms together to form a single entity.
The building consists of two volumes: the seminar centre with exhibition space, and the garage facility. The seminar centre cantilevers as far as the outer arrival area and part of the carpark. It rests on tall, very slender steel columns and functions both as a viewing deck and a protective roof above the entrance area. Beneath it the entire exhibition space develops in the form of a two-storey hall and is the first of a total of three spatial layers. They articulate the ground floor plan in a logical sequence: exhibition – sales – workshop. The circulation blocks are embedded in this plan.
